MINNEAPOLIS (AP) - Security is being boosted at the new Vikings stadium after a photographer gained access to the under-construction building.

The photographer, Scott Heins, published photos and an accompanying essay Wednesday on Deadspin.com.

In the essay, Heins said got in by pushing open a gap in the fence in May and then shot photos throughout the stadium, including some taken from a crane hundreds of feet off the ground.

In a statement, John Wood, senior vice president of stadium builder Mortenson Construction, said trespassing on construction sites is "illegal and very dangerous."

The statement also noted the company and the Minnesota Sports Facilities Authority, the public entity that oversees the stadium, are evaluating all options with local authorities to have Heins face consequences.
